Committed to results.

We are a procurement consultancy specializing in innovative methods for sustainable cost reductions and efficiency improvements.

Trusted partnerships, for over 20 years

Since 1997 we have been advising numerous international companies listed in DAX or Dow Jones, medium-sized businesses and public sector institutions. Our clients trust us because they know:  they get results from us with which they can work successfully.

Committed to results

Our unique combination of expert knowledge, international presence and experience leads to quickly measurable results and makes our clients' operations more profitable and efficient. “Committed to results” is not only an advisory approach but also our guiding principle.

The future might start just around the corner.

We are convinced that success comes along with social responsibility. Therefore, drozak Consulting promotes social projects on an annual and regular basis. In this way, we make a direct and measurable contribution to the society in which we live and work. The organizations we support are carefully chosen, according to their activities and whether they reflect our ideas of social responsibility. The commitment of drozak can be shown e.g. in the form of consulting projects, sponsorship or voluntary work.


When we look for suitable funding projects, we also look toward the future. That is why in recent years, we have focused on the youngest members of our society – and helped with the extension of a kindergarten or donated money to social children organizations.

Together we are drozak

What do you get when you combine excellent procurement knowledge, successful efficiency programs, clean value chains, powerful networks and extra psychological know-how? Probably not the very worst. See for yourself!
